Laparoscopic cholecystectomy as a safe and effective treatment for severe acute cholecystitis.

OBJECTIVE: To evaluate the feasibility and safety of laparoscopic cholecystectomy in severe acute cholecystitis. DESIGN: Analysis of data collected prospectively from a consecutive series of 350 laparoscopic operations. SETTING: Two general surgical units in a teaching hospital. SUBJECTS: 31 patients with a diagnosis of severe acute cholecystitis based on clinical examination, investigation results, and operative findings. INTERVENTIONS: Initial intravenous fluids and broad spectrum antibiotics followed by laparoscopic cholecystectomy within 72 hours of presentation. MAIN OUTCOME MEASURES: Failure to complete the operation laparoscopically, length of postoperative stay in hospital, early postoperative morbidity, interval from operation to full activity, and return to work. RESULTS: Laparoscopic cholecystectomy was attempted in 19 patients with empyema of the gall bladder and 12 who had severe cholecystitis which failed to settle on medical management. A total of 29 operations were successfully completed with two conversions to open surgery. Two minor postoperative complications occurred, and one case of retained common bile duct stones with jaundice was treated by endoscopic retrograde cholangiopancreatography and papillotomy. Median postoperative hospital stay was two days, with return to normal activity in seven days and to work in two weeks. There were no deaths related to the operation. CONCLUSIONS: In the presence of severe acute cholecystitis laparoscopic cholecystectomy is feasible in most patients, with minimal risk of injury to surrounding structures and considerable benefits. It is recommended that laparoscopic cholecystectomy should be attempted in these patients when appropriate surgical skill is available.

Cholecystectomy and adenomatous polyps of the large bowel.

Seventy two patients (39 women) with colonic adenomas were compared with 72 adenoma free controls (39 women) to investigate the possible association between previous cholecystectomy and the subsequent development of adenomas. Data were gathered retrospectively from medical records. Overall there was no significant association between colonic adenomas and previous cholecystectomy. When women are considered separately, however, eight cases and no controls had undergone cholecystectomy (odds ratio infinity lower 95% confidence limits 1.7, p greater than 0.01). No association between previous cholecystectomy and large bowel adenomas was found in men. Four of nine (44.4%) women with right sided colonic adenomas had undergone previous cholecystectomy compared with only three of 23 (13%) women with left sided adenomas.

Selective preoperative endoscopic retrograde cholangiography with sphincterotomy avoids bile duct exploration during laparoscopic cholecystectomy.

A policy of preoperative endoscopic retrograde cholangiography (ERC) for suspected bile duct stones was used in 1507 patients considered for laparoscopic cholecystectomy in three district general hospitals. Altogether 306 patients underwent ERC, and bile duct cannulation was achieved in 276 (90%). Bile ducts were cleared by endoscopic sphincterotomy in 128 of 161 patients (79%) with proven duct stones. Laparoscopic cholecystectomy was completed in 1396 patients. Ten laparotomies were necessary for complications of laparoscopic cholecystectomy. The complication rate for endoscopic sphincterotomy/laparoscopic cholecystectomy was 2.7%, with no mortality. Overall, a combined endoscopic/laparoscopic approach succeeded in 1386 patients (92%). Fourteen patients (1%) had retained stones during a median of 14 months (range 1-42) follow up, all of which were removed by ERC/endoscopic sphincterotomy. If a policy of selective ERC before laparoscopic cholecystectomy is used for all patients with symptomatic gall stones, most will avoid an open operation and laparoscopic exploration of the bile duct is not necessary.

Influence of cholecystectomy on sphincter of Oddi motility.

BACKGROUND: Gall bladder and sphincter of Oddi (SO) function are coordinated by hormonal and neuronal mechanisms. Nerve fibres pass between the gall bladder and the SO via the cystic duct. It is therefore possible that cholecystectomy may alter SO motility. AIM: To investigate the effect of cholecystectomy on SO function. METHODS: SO manometry was performed in five women (median age 52 years), a few days before and six months after laparoscopic cholecystectomy which was undertaken for uncomplicated cholelithiasis. Basal and post-cholecystokinin (CCK) SO motility were measured. RESULTS: All patients were symptom free after laparoscopic cholecystectomy. Prior to surgery common bile duct pressure, and tonic and phasic SO motility were normal and phasic contractions were inhibited by intravenous CCK (1 Ivy Dog Unit/kg). Six months later, common bile duct pressure and baseline tonic and phasic activity were unchanged but CCK failed to suppress phasic activity. CONCLUSION: Cholecystectomy, at least in the short term, suppresses the normal inhibitory effect of pharmacological doses of CCK on the SO. The mechanism of this effect is unknown but it could be due to SO denervation.

Patient recovery following cholecystectomy through a 6 cm or 15 cm transverse subcostal incision: a prospective randomized clinical trial.

The effect of incision length on patient recovery following cholecystectomy has not been investigated previously. In this study, 30 patients with symptomatic gallstones were randomized to cholecystectomy through a 6 cm or 15 cm transverse subcostal incision. Postoperative hospital stay was significantly shorter in the 6 cm incision group (median 3 days vs 5 days; P = 0.0069 Mann-Whitney U-test). In the 6 cm group analgesic requirements were reduced (median 2.5 vs 4.5 intramuscular opiate injections per patient) and recovery of depressed postoperative pulmonary function (FVC and FEV1) was faster (3% difference between groups on day 1 and 7% on day 3), although these differences did not achieve statistical significance. These results suggest that the length of incision may influence patient recovery following elective cholecystectomy. This has important implications as surgery carried out through shorter and less traumatic incisions may offer a cost-effective alternative to laparoscopic cholecystectomy. Moreover, some surgeons may find mini-laparotomy cholecystectomy easier to adopt than laparoscopic techniques.

Evidence for validity of a health status measure in assessing short term outcomes of cholecystectomy.

OBJECTIVE: To assess the validity of the Nottingham health profile (NHP) as an indicator of short term outcome of cholecystectomy. DESIGN: Prospective assessment of outcome. SETTING: One teaching hospital. Patients--161 consecutive patients admitted for cholecystectomy between January 1989 and September 1990. MAIN MEASURES: Patients' reported symptoms and self assessed NHP scores before cholecystectomy and at follow up at three and 12 months (76 patients); assessment before admission (19). RESULTS: Complete data were obtained preoperatively and at three months' follow up from 154 patients; seven did not respond to the follow up questionnaire. 76/84(90%) patients in the study 12 months or more answered the 12 month follow up questionnaire; eight did not respond. Significant changes in score before and at three months after the operation were observed for four of the six dimensions: energy (35.34 v 19.53, p < 0.0001), pain (27.38 v 9.8, p < 0.0001), sleep (26.99 v 17.51, p = 0.0002), and emotional reactions (16.12 v 7.56, p = 0.001). The mean scores for 76 patients followed up at three and 12 months showed little subsequent change. Scores in readmitted patients were all significantly higher, suggesting poor health. Patients with five reported symptoms had significantly worse scores for all dimensions. Scores were similar before cholecystectomy whether the questionnaire was completed before or after admission. CONCLUSION: The NHP is an appropriate tool for monitoring changes in health after cholecystectomy.

Complications of laparoscopic cholecystectomy and their interventional radiologic management.

Cholelithiasis and cholecystitis are encountered throughout the world and are responsible for the majority of cholecystectomies performed. Treatment has traditionally consisted of open cholecystectomy, but laparoscopic cholecystectomy is currently a popular alternative. Laparoscopic cholecystectomy offers several benefits over the open procedure, but it also has its own set of complications. Complications include those of laparoscopy (abdominal wall bleeding, omental bleeding, abdominal vessel injury, retroperitoneal vessel injury, gastrointestinal perforation, bladder perforation, solid visceral injury, and infection) and those of cholecystectomy (gallbladder fossa bleeding, bile duct injury, bile leakage, and infection). The literature suggests that the total complication rate for the laparoscopic procedure compares favorably with that of the open procedure, but this may apply only to surgeons who have accomplished numerous laparoscopic procedures and not to those who have just completed a training course and are performing their first few procedures. With the growing success of the laparoscopic procedure, it is essential that the radiologist be knowledgeable about the radiographic manifestations and interventional radiologic management of potential complications, since the radiologist can significantly affect patient care.

Partial cholecystectomy--safe and effective.

Patients undergoing surgical treatment for calculous disease were considered to have had a partial cholecystectomy performed when a part of the gall bladder wall was retained for technical reasons. Forty patients underwent partial cholecystectomy: for chronic cholecystitis (20), acute cholecystitis (4), Mirizzi's syndrome (14), portal hypertension or partially accessible gall bladder (one patient each). Four patients (10%) developed infective complications and two patients had retained common bile duct stones. In a mean follow up period of 13 months (range 1-36 mths), only 3 patients have ongoing mild dyspeptic symptoms while the rest have remained asymptomatic. Partial cholecystectomy has been found to be a safe and effective procedure in difficult cholecystectomy situations, since it combines the merits of cholecystectomy and cholecystostomy.

Laparoscopic cholecystectomy in cirrhotic patient.

Cholecystectomy is associated with increased risk in patients with liver cirrhosis. Moreover, cirrhosis and portal hypertension have been considered relative or absolute contraindication to laparoscopic cholecystectomy. As experience with laparoscopic cholecystectomy increased, we decided to treat cirrhotic patients via this approach. Between January 1994 and April 1995, nine patients with a Child-Pugh's stage A cirrhosis underwent elective laparoscopic cholecystectomy with intraoperative cholangiography. There was no significant per- or post-operative bleeding and no blood transfusion was necessary. There was no mortality and very low morbidity. Median hospital stay was 3 days. This series suggests that well-compensated cirrhosis can not be considered a contraindication to laparoscopic cholecystectomy.

The feasibility of laparoscopic cholecystectomy in patients with previous abdominal surgery.

A retrospective study was carried in 1500 patients submitted to elective laparoscopic cholecystectomy to ascertain its feasibility in patients with previous abdominal surgery. In 411 patients (27.4%) previous infraumbilical intraperitoneal surgery had been performed, and 106 of them (7.06%) had 2 or more operations. Twenty five patients (1.66%) had previous supraumbilical intraperitoneal operations (colonic resection, hydatid liver cysts, gastrectomies, etc.) One of them had been operated 3 times. In this group of 25 patients the first trocar and pneumoperitoneum were performed by open laparoscopy. In 2 patients a Marlex mesh was present from previous surgery for supraumbilical hernias. Previous infraumbilical intraperitoneal surgery did not interfere with laparoscopic cholecystectomy, even in patients with several operations. There was no morbidity from Verres needle or trocars. In the 25 patients with supraumbilical intraperitoneal operations, laparoscopic cholecystectomy was completed in 22. In 3, adhesions prevented the visualization of the gallbladder and these patients were converted to an open procedure. In the 2 patients Marlex mesh prevented laparoscopic cholecystectomy because of adhesions to abdominal organs. We conclude that in most instances previous abdominal operations are no contraindication to laparoscopic cholecystectomy.

Laparoscopic cholecystectomy: a multicenter study of 17 hospitals.

A study of 1,254 laparoscopic cholecystectomies performed at 17 hospitals affiliated with the Liver, Gallbladder, and Pancreas Research Group of the First Department of Surgery at Okayama University was undertaken to assess the current status and safety of this procedure. The data for 336 patients, comprising the initial 20 laparoscopic cholecystectomies performed at each institution, were compared with the data from the remaining 918 patients. Comparison of the two groups revealed the following: 1. the rates of intraoperative conversion to open cholecystectomy were 11.3% and 5.1% (P < 0.05), 2. the complication rates were 5.7% and 3.4%, and 3. the rates of bile duct injury were 2.4% and 1.1%, respectively. Compared with the first group, the bile duct injuries resulting from a lack of experience decreased in the second group, however, the incidence of these injuries occurring during avulsion of the gallbladder in difficult cases increased. These results suggest that the experience acquired during the initial 20 laparoscopic cholecystectomies led to a reduction in the rate of intraoperative conversion to open cholecystectomy, but it did not reduce the rate of complications, and that the risk of bile duct injury was always present.

Complications after laparoscopic cholecystectomy: imaging findings.

Laparoscopic cholecystectomy is rapidly becoming an acceptable alternative to traditional open cholecystectomy. Laparoscopic procedures are associated with shortened recovery periods and hospital stays and the cosmetic benefit of smaller scars. Early results from laparoscopic cholecystectomies suggested a high rate of complications; however, recent studies have shown that, in experienced hands, the complication rates of open and laparoscopic procedures are comparable. Complications differ somewhat between the two types of operations. In laparoscopic cholecystectomy, complications are associated with virtually every aspect of the procedure. The purpose of this essay is to illustrate the imaging findings of the complications that occur in patients undergoing laparoscopic cholecystectomy.

Routine operative cholangiography during laparoscopic cholecystectomy: feasibility and value in 107 patients.

OBJECTIVE: Laparoscopic cholecystectomy is becoming a popular alternative to open cholecystectomy. However, the technical aspects of this new procedure increase the risk of injuring the bile ducts. The purpose of this study was to determine the feasibility and value of performing cholangiography during laparoscopic cholecystectomy. MATERIALS AND METHODS: We retrospectively reviewed the clinical and operative cholangiographic findings of the first 107 patients undergoing laparoscopic cholecystectomy at Hôtel-Dieu de Montréal between August 1990 and August 1991. RESULTS: Operative cholangiography was attempted in 98% of patients; the success rate was 71%. Eight anatomic anomalies of the biliary tract that were of surgical importance were found as well as 10 cases of stones in the common bile duct, eight of which were unsuspected. No biliary tract injuries occurred. With experience, surgical cannulation of the cystic duct for injection of contrast material can be done quickly without major difficulty, and cholangiograms of excellent diagnostic quality can be obtained. CONCLUSION: Our results show that operative cholangiography is feasible and useful in patients undergoing laparoscopic cholecystectomy.

Complications of laparoscopic cholecystectomy: imaging and intervention.

Cholecystectomy is the most common abdominal operation done in the United States, with more than half a million cholecystectomies performed annually. Recently, there has been a trend to perform laparoscopic, rather than open, cholecystectomy. The introduction of any new technique involves a learning curve for surgeons, and several complications may occur with this procedure. Radiologists may be called on to help diagnose and manage injuries occurring after laparoscopic cholecystectomy. This article will review the complications of laparoscopic cholecystectomy, emphasizing the role of imaging in both diagnosis and nonsurgical management of these injuries.

What are the indications for cholecystectomy?

Cholecystectomy is indicated in the presence of gallbladder trauma, gallbladder cancer, acute cholecystitis, and other complications of gallstones. More controversial are the indications for elective cholecystectomy. To properly determine the indications for elective cholecystectomy, the risk of the operation (taking into account the age and comorbid factors of the individual patient) must be weighed against the risk of complications and death without operation (taking into account the symptomatic status of the individual and the functional status of the gallbladder). Cholecystectomy (or some other form of gallstone therapy) is indicated in most patients with symptomatic cholelithiasis--especially those with non-functioning gallbladders. Cholecystectomy is not indicated in most patients with asymptomatic stones.

Prophylactic cholecystectomy or expectant management for silent gallstones. A decision analysis to assess survival.

Decision analysis was done to compare the consequences of prophylactic cholecystectomy with expectant management for silent gallstone disease. Probability values were derived from a study of the natural history of silent gallstone disease, published cholecystectomy mortality rates, and life tables. The two strategies were compared by calculating cumulative numbers of person-years lost for hypothetical cohorts of men and women. Prophylactic cholecystectomy slightly decreases survival. A 30-year-old man choosing prophylactic cholecystectomy instead of expectant management would lose, on average, 4 days of life; a 50-year-old man would lose 18 days. Consideration of monetary costs and discounting further disfavors prophylactic cholecystectomy. Sensitivity analysis shows that differences between the two strategies remain small over a broad range of probability values, both for men and women.

[Endoscopic retrograde cholangiopancreatography prior to laparoscopic cholecystectomy in patients with suspected choledocholithiasis].

BACKGROUND: Laparoscopic cholecystectomy is the treatment of choice for patients with symptomatic gallstones. The management of choledocholithiasis in these patients remains controversial. Endoscopic retrograde cholangiopancreatography (ERCP) with ductal stone clearance prior to laparoscopic cholecystectomy is one of the options. OBJECTIVE: To evaluate the results of ERCP prior to laparoscopic cholecystectomy in patients with suspected ductal stones. METHODS: We performed a retrospective study from patients who underwent ERCP prior to laparoscopic cholecystectomy in a four years period. RESULTS: ERCP was successful in 86 out of 88 patients (97.7%). Common bile duct (CBD) stones were found in 34 patients (39.5%). Sixty two of 86 patients had symptomatic gallstones with abnormal liver function test and/or ultrasound. CBD stones were found in 25 of the 62 symptomatic patients (40.3%). Twenty four patients had acute biliary pancreatitis. CBD stones were found in nine of these patients (37.5%). All patients with CBD stones underwent stone extraction after endoscopic sphincterotomy (ES). Sixteen other patients underwent ES for suspected obstruction at the ampulla. Stone extraction was successful in 100% of patients. There were six patients with complications (6.9%). Four patients had pancreatitis (4.6%), one patient hemorrhage (1.1%) and one patient cholangitis (1.1%). Analysis using logistic regression model showed that CBD stones on ultrasonography was the only variable significantly associated with choledocholithiasis (P < 0.001). CONCLUSIONS: Preoperative ERCP is useful in the management of CBD stones prior to laparoscopic cholecystectomy.

The role of cost analysis in deciding whether to provide laparoscopic cholecystectomy in remote communities.

To review the role of cost analysis in deciding whether to provide laparoscopic cholecystectomy in a remote community, cholecystectomies for Baffin Region residents were reviewed. Actual cost was calculated using known travel costs, per diem costs, and length of stay (LOS) data. Laparoscopic cost was estimated using LOS and conversion data from the literature. Between 1992 and 1995, 72 patients from the Baffin Region had a cholecystectomy, 61 in Iqaluit and 11 in Montreal. Fifty-seven and five, respectively, were suitable candidates for laparoscopic surgery. LOS was 5.6 days in Iqaluit and 3.5 in Montreal. Annual cost was $167,465 (Canadian). Comparable laparoscopic cholecystectomy cost is $45,411, an annual saving of $122,054. Even after equipment depreciation, laparoscopy provides a calculated saving of over $100,000 a year. However, even maximal decrease in bed utilization is less than 0.5 bed per day. Such small decreases do not allow staffing reduction and, thus, most of the projected savings cannot be realized in practice. Therefore, neither costs nor savings can play a supportive role in a decision to provide laparoscopic cholecystectomy in remote communities. This decision would have to be based on other considerations.
